It's the same with
Revolut for Cyprus & Malta.
Most likely becaue of pressure from the EU as Wise is Belgium based and Revolut Lithuania based.
I'm pretty much sure that they receive as by far the biggest
EMI's in EU some pressure from the EU to not make it too easy for EU nationals switching there base to the islands - BoC and all Malta banks already reflect this since years.
Furthermore both relay on correspondence network and therefore you couldn't send with
Cyprus Company USD with Wise since forever.
The best replacement if you deal with EUR is
Paysera as they give you dedicated SEPA/SWIFT IBAN via TARGET2.
However when you deal with USD you can't work with EMI's as no other EMI actually really provides you with a facility like Revolut / Wise does.
You can only stick to a few
high risk EMI's that charge you an Arm and a Leg for transfering around - see Wallter they have a St. Lucia based Correspondence Bank and chagre you flat % for incoming and outgoing up to 5%.
I have seen them recently being used by a lot of clients based on Cyprus switching to Dubai - as there is no other possibility actually for those opening Cyprus lately - Malta is already longer a problem - they stopped already in 2019/2020 onboarding Malta and now with the FATF grey listing it's even getting more worse.
A waitlist is always a nice looking excuse:
Take a look on moneynetint.com they have actually a waitlist as well but not because they want to - it's because there daughter company Globalnetint has regulator issues in Lithuania:

Ask yourself if you want to count on small islands in 2021.
I'm pretty sure like
@Martin Everson said as well - Malta & Cyprus are easy targets to set an example from EU as they don't have any economy beside of getting you CySec CFD licenses & Gambling licenses.
